CHECK-PRINTER ATTACHMENT FOR CASH-REGISTERS.

Application filed June 30, 1910. Serial No. 569,833.

To all whom it may concern Be it known that I, BYRON, BLiss WELLS, citizen. of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Check-Printer Attachments for Cash-Registers, of which the following is. a specification.

This invention relates to a check printer attachment for cash adding machines.

An object of the invention is to provide means whereby the issuance of checks from the check rinter may be controlled to correspond with certain conditions.

, A further object of the invention is to provide means whereby a check may be issued by the check {printer with all the transactions represented by the department keys of the cash adder, or with any one or more of them, or may be withheld entirely.

A further object of the invention is to provide means whereby the check printing devices are locked against operation until after a partial operation of the adding mechanism.

A further obj ect of the invention is to provide means whereby the adding mechanism, after a partial operation of same, is preventedfrom' further complete manipulation under certain'conditions until after anoperation of said printing devices;

A further object of the invention is to provide means whereby, after a partial operation of said adding mechanism, under conditions where the machine is set to issue checks, theissuance of the check maybe optional with theproprietor; means being provided for permitting the complete operation of the said adding mechanism without first operating the printing devices. I A' further object of the invention is to provide a machine of the character referred to in which all danger of erroneous operation and also manipulation is obviated, the operatorbeing compelled to operate the machine in a proper manner to issue checks to conform with. the transaction made upon the adder and also to conform with the controlling devices.

The invention consists in the constructions and combinations of parts hereinafter described and set forth in the claims.

Fig. 8 is an Fig. 19 is a view of a i Printing dem'oes.The check printer which I' have shown in thedrawings is of a. well known type, so far as the printing of the checks is concerned, but the construction thereof will be described asfollows; 1 and 2, respectively are side plates or frames joined together byspacing rods 3; these frames carrying the operating parts of the printer, such as the date and consecutive number'printing cylinder 6, the advertisement printing. cylinder 7, the impression rolls 8 and 9 for the same, (all of which are geared together), the inking rolls 10 and 11 for same, the check printing wheels 5, the check impression hammer and paper cutoff 12 and the paper guide 13. The side plate 2 is secured to the bosses 14 on the slde frame 15 of the cash adder.

The check printing type carrying wheels 5 are mounted loosely on their shaft 17, and each wheel has a pinion-16 concentrically secured thereto. Each of these pinions is meshed with a gear segment 19; all of sa d segments being mounted loosely on the main shaft 18 of the cash register. Riveted to each segment is an extension 20 (Fig. 2); these extensions being of graduated lengths and having secured to their outer ends straps 21 which extend into the cash adder and are there secured to upwardly projecting arms 22 (Fig. 10) on the hubs of graduated segments 23. These segments 23 are the usual segments found in a machine of this type, said segments having the usual rearwardly extending yokes 23 which are supported by the main operating lever 88 and drop when the cash drawer opens, their movement being limited by the depressed key 24 of any series. It will be understood that one type wheel 5 is provided for each cash denomination respectively upon the key board, as well as for the department bank of keys and that there will be one segment 19 for each type wheel and each segment 19 will be connected with the segment 23 corresponding thereto, so that as any segment 23 drops it will cause its corresponding type wheel 5 to move to correspond with the key of that denomination, or department bank depressed. Also loosely mounted on the shaft 17 is a U-shaped frame 25 (Figs. 2, 5 and 11) between the side arms of which extends a rod 26 on which swings an ink pad holder 27 having fingers 28 which extend rearwardly between the type wheels 5.

To a stud on the short arm 29 of the frame 25 is attached one end of a link 30 which ex tends rearwardly and is forked to straddle the shaft 31 which has its hearings in the side frames 1 and 2 and which carries a wheel 32 in which is cut a cam 33 into which extends a stud 34 on the link 30 so that when the wheel 32 revolves the frame 25 is caused to swing downwardly so that the ink pad 35 is brought under the type wheels 5, in which position it is struck by the impression han1- mer 12, inking the type, as will be described farther on. The frame 25 is then returned to its normal position as the cam wheel 32 completes its rotation; it being understood that said cam wheel is geared with the gearing previously referred so as to move therewith when operated in manner more fully described hereinafter. The dating and con secutive numbering cylinder consists of a barrel 36 (see Figs. 14 to 17 inclusive for detail) having a ournal 37 integral therewith and extending through the side plate 2. The opposite end is fitted with a cap 38 which extends through the side plate 1.

The barrel 36 is chambered longitudinally to receive the dating and numbering type wheels 39 and 40 respectively; also the ratchet members for rotating the same. The dating wheels 39, three in number, are rigidly mounted on sleeves 41, 41 and 41 which project through the cap 38 and ha e secured to their outer ends correspondingly named and numbered wheels 42 by which said date type wheels 39 are set to their proper printing position. Ashaft 43 extends through the sleeve 41 to the opposite end of the barrel 36 and on this shaft are loosely mounted consecutive numbering type wheels 40 and a U-shaped frame 44 which carries a pawl 45. The pawl 45 has a series of fingers which correspond to the number of type wheels and which engage ratchet teeth on the side of each wheel. These fingers are of graduated lengths and each ratchet wheel has a deep notch into which its finger drops so that the next finger may engage the ratchet of the wheel of the next higher denomination in a well known manner. Overthrow and backward movement of the wheels 39 and 40 are prevented by springpressed pawls 46 mounted on the rod 47 which lies parallel to the shaft 43 and is supported at its ends by the end of the barrel 36 and its cap 38. A stud 48 extends from the swinging pawl-carrying frame 44 through a slot in the end wall of the barrel 36 into a cam race 49 on the side of the cam wheel 50. The wheel 50 is concentric with barrel 36, but is held from rotation therewith by the pin 51 which projects from it into the side frame 2. The shape of the cam race 49 is such that as the barrel 36 makes a coinplete revolution the pawl frame is caused to oscillate a distance sui'licient to enable the pawls to move the unit wheel forward one-tenth of a revolution, and then return. The wheels may be set to zero by pressing thereon with ones fingers. On the barrel 36 may also be secured type for printing any other desired information or advertisement. Partly surrounding the barrel and cap are annular flanges which press on the paper near the edges whereby the paper is drawn from the roll in the usual manner during a portion of the rotation of the cylinder 6.

The rear cylinder 7 which prints the under side of the check consists of a shell adapted to rotate on a rod 52 which is supported in the plates 1 and 2 and upon which type may be secured.

Pressure on the type of both the front and rear cylinder 6 and 7 is provided by the impression rolls 8 and 9 which consist of steel shells covered with vulcanized rubber and rigidly mounted on shafts 53 and 54 respectively. The roll 8 is also provided at each end With a cam wheel 55, the purpose of which will be described more fully later.

Ink is supplied to the type on the cylinders 6 and 7 by means of the inking rolls 10 and 11 which consist of a shell of felt mounted on a tube through which extends the rods 56 and 57 and are supported in the side plates 1 and 2.

A stationary knife block 58 is secured at its ends to the plates 1 and 2 forward of the front cylinder '6 and is gained to receive a tool steel knife blade 59, which is fastened thereto.

The impression hammer 12 consists of two side bars 60 joined by cross-bars 61,- 62, 63,

and 64. The bars 60 are'fulcrumed at their '70. Rollers on studs 71 project inwardly from the side bars 60 of the hammer into cam races 72 in the side of the cam wheels 55. The cam races 72-are so formed that as the cylinder 8 revolves the hammer 12 is raised twice, the first time but slightly, when the ink pad is brought under the check type wvheels, whereby the pad is forced into contact with the type and'afterward it is raised sufiiciently higher to press the check into contact with the type, the paper having been fed through before the latter hammer movement. The first movement of the hammer is not suflicient to bring the knife to the paper but on the second movement the check is cut ed.

The operation of the date and consecutive numbering cylinder 6. the printing cylinder 7, the impression rolls 7 and 8; and the shaft 31 which carries the cam wheel 32, is caused by power applied to the hand lever 73 (Figs. 2 and 6), which is fulcruined on the main shaft 18 and which has on its opposite end the gear segment 74 which meshes with the pinion 74 loosely mounted on the stem or journal 37 (see Fig. 9) to which is secured the disk 74 which carries the spring pressed pawl 75 which is adapted to drop in to the notch 7 6 formed on a collar 76 which is rigidly secured to the stem 37 the contogether, some of the gears being indicated thus unlock the printing mechanism.

Adder eon-trolled locking devices for 791'z'nte1'.-Means are provided for normally preventing the operation of the printing devices until after a partial operation of the adding mechanism and also for preventing the operation of the register during the printing operation, the devices for accomplishing this being as follows: A cam wheel 77 is secured to the impression roller shaft 54: on the outside of the side frame 2. (See Figs. 2, 6, 7, and 8). A lever 81 (Figs. 2, 6 and 7) fulcrumed on a stud 82, projecting from the cash adder frame 15, has its rear end formed with a toe 83 which normally extends into the notch 81 in the cam wheel 77. The upper face of the upward end of the lever 81 lies tangentially against the periphery of the cam 85, which is loosely mounted upon the shaft 18 and which has a rearwardly projecting arm 86 to which is secured one end of the gravity bar 87; the opposite end of said bar being secured to a similar arm loose on the shaft 18 at other end of the cash register. The bar 87 is normally supported by the main operating lever 88 (see Fig. 10), which main lever 88 is fulcrumed on the shaft 18 with its lower end resting on the roller 89 on the cash drawer 90 in a manner common to adders of the type shown so that when the cash drawer opens the main lever will drop and permit the arm 86 to also drop and assume the posi tion shown in Fig. 7, in which position the cam 85 will ride off of the upper end of the lever 81 and permit said lever to be rocked by the spring 81'-so as to withdraw its toe 83 from the notch in the cam wheel 77 and It will be observed that this unlocking of the printing devices does not take place until the cash drawer has reached practically its complete open position for its purpose hereina-fter explained.

It will be observed that the end of the lever-81 and the shoulder formed by the cam 85 have corresponding beveled surfaces so that as the parts are returned to normal position thelever 81 will be rocked back to lock- "-1? notch 81- coincides with the toe 83 on said lever, so that the registering mechanism will be locked until the printing operation has been completed. After the adding mechanism has thus far been partially operated and the printing mechanism unlocked, additional means are also provided for preventing the complete operation of the adding mechanism until after the complete operation of the printing devices, but this means will be described hereinafter.

Transaction controlled locking devices for T printing cZeres.-Adjacent the cam wheel 77 previously described is a locking plate 78 having slotted openings through which pro ject the stem 37 of the cylinder 6 and the end of shaft i. (Figs. 3, 6, 7 and 8 for detail). This plate carries a laterally projecting stud 79 which projects into a cam race on the side of the cam wheel 77. The forward part of said cam race is provided with an abrupt shoulder 80 so that when the printer is in its normal position, the stud 79 of the locking plate will lie just above the shoulder 80 thus locking the shaft 5%, and hence the printing devices, from movement. in order to unlock the parts, means are provided, upon the operation of the registering mechanism, tor moving the locking plate rear wardly so as to bring its stud out of the path of movement of said cam shsoulder, so that when the cam 77 is revolved the said stud will be free to pass into the concentric part 80 of said cam race, the final quarter 80 of which, being eccentric, again forces the plate forwardly to the locking position. These unlocking means, however, are controlled by devices which cooperate with the keys 2st of the adding mechanism which determine the transactions; that is to say, the mechanism may be so set as to issue a check with all of the transactions represented upon the keyboard the adder; it may be so set as to prevent the issuance of checks altogether; or it may be so set as to permit the issuance of checks with but certain of the transactions. First: Normally, the operation of unlocking the printer and the issuance of checks is under the control of setting devices associated with certain keys in the key board of the register which represent certain transactions such as Received on account Charge, Cash etc, a setting device being provided in connection with each of these keys which determines, upon the depression of any key, whether or not the print-er will be unlocked upon the first partial operation of the register mechanism;

this condition being the normal condition of the lock controlling devices. Secoperate therewita, so that it will be impossible to issue check at all; this condition of the devices being hereinafter referred to as the position. Fourth: in addition to the three conditions mentioned, there is also provided a device by which, after the partial operation of the register mechanism and after the printer has been unlocked thereby so as to permit its operation, the complete operation of said adding mechanism may be performed without operating the printer; this device being known and hereinafter referred to as the optional device. In connection with this condition, it may be stated here that after the registering mechanism has been partially operated and the printer unlocked, said registering mechanism is normally locked against further operation until after the complete operation of the printer, and this adder locking device will be described more fully hereinafter.

Normal conclitz'on.l3eterring to Figs. 1, 2, 3 and l, the bank of keys 2 lshown is what is known as the department key bank, which represents such transactions as No sale Paid out Charge, Received on account, Cash, and different departments of the store or dilierent classes of merchandise a release key 2% for releasing the other department keys that have been depressed being also included in this bank, this release key being in the present case the lower-most key of the series. These keys are of the or dinary kind found in registers of this type and are adapted to form stops when depressed ter the segment 23 corresponding thereto so as to determine the movement of the parts to indicate on the register and print on the check characters corresponding to the key depressed. These keys are held in depressed position by the detent plate 137 (Fig. which has hooks that engage laterally-extending pins M0 on the keys in a manner which is common in adders of this type. T he simultaneous depression of two or more keys is prevented by means of an interference plate 135 located between the key A frame 136 and detent plate 137; this interference plate being loosely mounted on the shaft 18 and is supported in its normal position by the rod 9%. The forward edge is concentric to said shaft 18 and has radial slots 13-8 and inclined faces .39 leading thereto from the lateral. pins 1 H) spaced in such a manner that two or more pins cannot enter their respective slots at the same time far enough to be retained by the hooks in the detent plate, with the single exception of the release key, (whose lateral pin is represented by 1&1, 12), which releases any depressed key of the series, which it does by raising the detent plate which permits the depressed key to spring out by the tension of its spring This rel asing may be accomplished at any time before the drawer role key 300 is depressed.

Located adjacent the left side or the key at each end of said plate as shown in Fig. 3. 1

A- second plate 95 is rigidly secured to the outside of the adder frame 15 (Figs. 2, 4 and 18), and a third plate 96 lies adjacent to the plate 95 and is supported on shoulder screws 96 which pass through slotted openings therein, permitting a slight end-wise movement, as shown in Fig. 1. The respective plates are provided with notches or oblong holes 96 95 and 92 near their outer peripheries, which notches and holes register with each other and receive sliding bars 97, one for each key of the bank. The inner end of each bar, when in normal position, projects a short distance inside the plate 92 but out of the line with the stems of the respective keys. These bars 97 have an endwise movement, the extent of which is controlled by the projections 97 97 and 97 on their lower edges. WVhen any one of these bars is pressed in to the limit allowed by the projection 97, the end of said bar will lie in the path of movement of a sphne 98 on the under side of the key stem corresponding thereto, the inner end of the spline being beveled so that as the key is depressed it will bear downwardly on the bar 97, which, being fulcrumed on the stationary plate 95, will give to the plate 92 a downward movement. The plate 96 is drawn down against the tops of the respective bars 97 by a spring 99, (see Fig. 1) which serves to hold the said bars yieldably in adjusted position. 7

The lower end of the plate 92 rests against the upper edge of a controlling plate 100 (Fig. 3), a spring 100 tending to hold said plates 100 and 92 in an upward position, and fromthe face of said plate 100 projects a lug 101, which, when in its normal position, lies in a notch in the forward end of a lever 102. The lever 102 is fulcrumed on the shouldered screw 103 in the adder frame 15 and has an arm 104-. projecting down therefrom, the lower end of which arm nor: mally extends a short distance forward of the stud 106 which projects laterally from the forward end of the locking plate 78 previously described. An arm 107 projects up wardly from said lever 102 on the free end of which is a pawl 108 pivoted at 108 the lower end of which pawl is normally but a short distance above the point of the cam projection 109 which extends laterally from the cam 85 previously described, so that when the lever 102 is rocked by the depression of a key as described above, the point of the pawl 108 is brought below the cam 109, and the arm 104 in close proximity to the stud 106. A boss 14: on the frame of the adder, against which the upper end of the arm 107 contacts forms a stop for the lever 102 which is normally swung upwardly by the spring 104.. The operation of these de vices is as follows.

By. means of the bars 97 the proprietor enabled to determine the character of the transactions upon which he desires, to issue or not to issue checks. For instance he may want to offer a rebate on cash sales and therefore issue av check upon each cash sale; or he may. want to issue checks on certain classes of goods represented by the department keys upon which there is a good profit, but not upon other classes of goods. When it is desired to issue a check on a certain transaction the bar 97 corresponding to the key representing that transaction is moved to the right so that the end thereof will be engaged by the spline 98 when the key is depressed and pushed downwardly where upon the plate 92 is. also pressed down against the lever 100, and the projection 101 thereon rock the lever 102 against the tension of its spring 101 suflicient to bring the arm lOatinto contact with the stud 106 of the locking plate, and also bring the point of the pawl 108 below the point of the cam 109. The lever 102 is now set so that as the gravity bar 87 isallowed to fall by the opening of the cash drawer of the register, the cam 109 will ride over the top of the pawl 108 and thus further, rock the lever 102 and cause it to push the locking plate rearwardly and thus unlock the printing mechanism. in the manner previously described. The printing mechanism may then be operated and in order to insure the operating of the printing mechanism before the completion of the registering operation or pushing in of the cash drawer, I have provided means, as before stated, for locking the registering mechanism until after the complete operation of the printing device, which means will now be described.

Lock for registering meehanism.Upon the shaft 117, which extends across the back of the register and has its bearings in the side plates thereof, are two arms 118 and 119. A stud 120 (Fig. 6) projects laterally from the arm 118 into an angularly slotted opening 121 in the locking plate 78 previously described. As the gravity bar 87 falls to operated position the locking plate 78 will be thrust rearwardly as before described and the stud 120 on arm 118 will be at the forward end of slot 121, and so soon as said gravity bar rides over the arms 118 and 119 said stud will be raised to the highest point of said slot by the spring 122 whereby the shaft-bar 117 with the arms 118 and 119 are rotatedupwardly into the path of the gravity bar and thereby locks the same and likewise prevents the closing of the cash drawer until the sliding locking plate 78 is again moved forward by the cam 80 and the arms 118 and 11-9depressed by the inclined face of the slot 121 pressing on the stud 120.

0;? position of printer loclc operating dem"0es.Means are provided for throwing out of operation the operating devices for the printer lock so that the printer will remain locked under all conditions, irrespective of the key operated controlling means, so that it will be impossible to issue a check with any transaction whatsoever. The plate 100, it will be seen, is extended downwardly and its free end pivoted on a pin 111 which projects eccentrically from the end of the short shaft 112 which has its hearings in the casing 118 and a side plate of the register. on the outer end of the shaft 112 is a lever 111 by which the shaft 112 may be turned to the desired position. hen the pin 111 is in mid position, as is shown in Fig. 3, the conditions of operation are normal, as first described; that is, the issuance of checks is under the control of the key operated devices. By turning the shaft to the left, the pin 111 will thrust the projection 101 on the plate 100 upwardly above the notch in the lever 102 where it will manifestly have no effect on the lever 102 when the plate 92 is forced downwardly by the depression of the key, and consequently the cam 109 will pass under the pawl 108 which yields upwardly against the tension of its spring 108 thus leaving the printer in locked condition. It will be seen also in this case that the locking arms 118 and 119 willbe held in an inoperative position by reason of the fact that the locking plate 78 remains stationary so that the cash drawer of the machine may be pushed back to closed position irrespective of any operation of the printing device.

0n position of printer Z0070 operating (Zem'ces.i3y turning the shaft 112 in the op- I posite direction it will be seen that the plate 100 is drawn downwardly and with it the lever 102 so that the projecting arm 104 will lie adjacent the stud 106 on the locking lever and the po nt of the pawl 108 will be below the cam 199 so that the printer will be unlocked at each operation of the register regardless of the positions of the operated bars 97. Such a position of the operating devices is desirab e when the proprietor wishes to issue a check with each transaction.

Optional dam er-From the description so far, it has been seen that whenever the printer devices are unlocked by the first operation of the adding mechanism, said adding mechanism becomes automatically locked against further operation until after the complete operation of the printer. It has been further seen from the description that in cases where it is not desired to issue checks upon any transaction, the printer remains locked and the adding mechanism unlocked. In other words, after the first par tial operation of the adding mechanism, either the printer becomes unlocked and the adding mechanism locked or the printer remains locked and the adding mechanism is prevented from becoming locked; that 1s,

either one of the two is locked. In addition to these conditions I have further provided means whereby after the first operation of the adding mechanism the printing devices may be operated or not at the option of the operator, and in order to accomplish this I have provided means for preventing the lock for the adding mechanism from moving to locking position. This optional device is best shown in Figs. 2 and 10.

It will be remembered that the shaft 117 carries the arms 118 and 119 which form bars against the return to normal position of the gravity bar 87 and thus lock the adding mechanism against complete operation until after an operation of the printer, which printing operation causes the locking plate 78 to rock said arms 118 and 119 out of the path of the movement of said gravity bar 87. The shaft 117 also has a depending arm 125, the lower free end of which is con nected to the bar 126 by the stud 127 which extends through the slotted opening 128 in said bar. The bar 126 extends forwardly and has a shoulder 129 which is adapted to be engaged by the stud 130 which extends from the arm 131 rigidly fixed to the rod 182. The normal position of the parts is that shown in Fig. 10 in which the shoulder 129 is out of engagement with said stud, being held in this position by the spring 183, and in this position the shaft 117 is free to rock so as to permit the arms there on to lock the gravity bar.

By pressing the rod 126 rearwardly, the forward end of the slot 128 is brought against the end of the stud 127 and this prevents the oscillation of the shaft 117 and arms 118 and 119, so that the gravity bar 87 will not be locked thereby and is not prevented from immediately returning to normal position, so that the operator may at his option either operate the check printer and to issue a check or complete the full op eration of the adding mechanism independent of said printer and without issuing the check.

It will be understood of course that this optional device does not interfere in any way with the issuance of checks upon separate transactions; that is to say, even though the optional device was in operative condition to prevent the locking of the register mechanism, the printer locking device would still be under the control of the bars 97 so as to unlock the printer or leave it locked according as to how the said bars 97 are set.

Make-sure (lei-ice for printer Z0c7s.In order to insure the proper return to locking position of the locking plate 78 after each operation of the machine, independent of any operation of the printer, I have provided means for positively throwing said plate forwardly so as to bring its stud 79 in proper locking relation with the shoulder on the cam Wheel 7 7 One of the devices for accomplishing this purpose is shown in Figs. 3 and 6. A plate 400 (Fig. 6) is slidingly mounted upon headed screws 4.01 secured in the frame of the adder and which extend through slotted openings in said plate. The rear end of this plate has an upturned projection 402 which stands in line with the stud 106 on the forward end of the locking plate 78. A spring 403 normally holds this plate in its rearmost position. The forward end of the plate also has an upturned projection 40% which stands in the path of movement of the pin 105 secured to the shaft 112. When the lever 1H is turned to off position this pin 405 will strike the projection 101 and move the plate 4:00 forwardly, thus causing the locking plate 78 to be likewise moved forwardly in looking position by reason of the contact of the projec tion 4:02 with the stud 106. It will be understood that the devices thus described operate only when the controlling index lever 11% is turned to off position.

In addition to the above device, I have alsoprovided means for insuring the return of this locking plate 78 to locking position at end of each complete operation of the machine. In Fig. 6, 500 represents a lever pivoted at 501 to the adder frame and having its upper end standing adjacent the rear end of the said locking plate. After the cash drawer opens it will be seen that the locking plate 78, upon its rearward movement to unlocking position will swing its lever 500 so as to bring its lower end into the path of the cash drawer so that as the cash drawer is again closed it will swing said lever back to normal position and cause it to also move the locking plate 78 to its locking position in case said 100 ing lever should not have been returned to said position by the usual means heretofore described.
